TagFly on new websites

1. TagFly appeared on 3 new sites in the last 30 days.^[1]

The line is the 7-day average share of new sites that use TagFly, over the last 90 days. It starts at our first detection. The shaded area was measured against a different set of sites, so the line can step there without TagFly itself changing.^[2]

All-time shares across the new sites we track: of all of them, and of the sites using any Tag Management tool. All 39 in Tag Management

None of them is a product launch we list individually, so there is nothing to show here. They still count towards the figures above. How StackScope Discovery works

The StackScope API serves all 21 sites using TagFly, filterable and exportable, from £15 a month.

1. These figures cover websites that went live since April 2026, not the web as a whole.
2. Amber: 8 July to 10 September 2026, before we improved our infrastructure to index new sites much sooner, often on the day they go live. Sites found that early often haven't finished setting up, so anything usually added after launch reads lower from 10 September. We record each site as it was when we found it.
